...formation? When in formation and the center has the ball prepared to hike to the quarterback...before he does, he will sometimes, with one of his arms outstretched, point either at the player across from him or downfield. What is this about? What is he pointing at? Why does he do this on some plays and not others? How does he keep from hitting the player across from him per his outstretched arms? If the defense rushed per the centers movement of his outstretched arm would the defense be wrong and why?
